Thanks
Really appreciate you posting this, as I'm just days away from riveting on my aileron hinge brackets. I'm sure there are others out there in a similar situation.
Cheers,
Tom.

What a disappointing development. Does anyone know how many reports of this type of cracking Van's received prior to issuing the SB?
It sure would be nice if Doug set some sort of database where people could report and share their findings as they execute the inspection portion of this SB  . The data should be available fairly quickly given the direction to inspect before further flight. |

It would be nice to receive an "inspect before further flight" by an email notice. Not that I'm asking for more SB's.

Steve,
I agree.
On another note, I posted up a message over on the General Discussion forum to drive folks over here.
I was just killing time on a Saturday night and rarely check this part of VAF. Would have been weeks before I'd seen it otherwise.
Pretty important SB to be buried off the main storefront, so I gave a heads-up.
Rob

Is this a first for Vans? SB notes that there is a charge if you need parts.

Thank you Bernie for posting this, it is really appreciated...
''SB notes that there is a charge if you need parts. '' Amazing that we have to pay for parts to fix a design problems...

Nope. Welcome to the club. Good news, the SB kits are usually inexpensive. It's the errors installing them that cost. 
BTW, anyone notice the rivet on the bracket in the SB are installed backwards. I suspect most are done per Mil-Spec and installed with the factory side on the forward side of the aft spar. Drilling the shop side will be a bit more tricky.

Quote from SB: It is unlikely that RV-6/6A wings will be affected. If cracks are present in RV-6/6A aircraft, email Van’s Engineering Dept for instructions, with photos of the cracks, for a specific repair scheme.
Curiosity question. What is different about the -6/6A wing that makes it unlikely that cracks would occur?
I'm a non-builder.

Another non-builder question....
What's causing the cracks that are being seen?
Assembly error? Fatigue? Something else?
Which wings are they happening on? QB? SB? Both?
